Definitions

  • the present invention relates to a tobacco filter used in producing a hand-rolled cigarette by wrapping a smoking plant such as tobacco leaves or herbs for smoking with a wrapping paper.
  • a tobacco filter having a shape which enables easy wrapping of a wrapping paper around a smoking plant and enhancing absorption of harmful substances such as tars when smoking.
  • a popularly-used filter of the hand-rolled cigarette has the same size as the commercially available cigarette, that is, is small and short. Because of being small and short, the production of a hand-rolled cigarette with a filter using the hands requires a skill to some extent. To compensate for this insufficient skill, it is often the case where a personal tobacco wrapping device is used in the production of a hand-rolled cigarette with a filter.
  • Fig. 13 is a top plan view of the personal tobacco wrapping device 40.
  • the personal tobacco wrapping device 40 includes a fixed tobacco-wrapping roller 22A, a movable tobacco-wrapping roller 22B, a tobacco-wrapping belt (not shown in Fig. 13 ) and a frame 25.
  • Fig. 14 is a perspective view of the personal tobacco wrapping device 40 where the frame 25 is not shown in the drawing.
  • the fixed tobacco-wrapping roller 22A and the movable tobacco-wrapping roller 22B have a columnar shape respectively, and a shaft 24A of the fixed tobacco-wrapping roller 22A and a shaft 24B of the movable tobacco-wrapping roller 22B are arranged parallel to each other. Further, as shown in Fig.
  • both ends of the shafts 24A, 24B axially project from the fixed tobacco-wrapping roller 22A and the movable tobacco-wrapping roller 22B respectively, and are mounted on the frame 25 such that the fixed tobacco-wrapping roller 22A and the movable tobacco-wrapping roller 22B are not disengaged from the frame 25.
  • the fixed tobacco-wrapping roller 22A is rotatable about the shaft 24A
  • the movable tobacco-wrapping roller 22B is rotatable about the shaft 24B.
  • a smoker can make the movable tobacco-wrapping roller 22B approach the fixed tobacco-wrapping roller 22A by pushing the movable tobacco-wrapping roller 22B with his finger or the like.
  • the shaft 24B moves along elongated holes (not shown in the drawing) formed in the frame 25 and approaches the shaft 24A.
  • the movable tobacco-wrapping roller 22B moves in the direction toward the fixed tobacco-wrapping roller 22A.
  • the movable tobacco-wrapping roller 22B can move in the opposite direction as well.
  • the movable tobacco-wrapping roller 22B can make a separating movement where the movable tobacco-wrapping roller 22B is separated from the fixed tobacco-wrapping roller 22A.
  • the rotational movement of the movable tobacco-wrapping roller 22B and the approaching and separating movement of the movable tobacco-wrapping roller 22B in the direction toward and away from the fixed tobacco-wrapping roller 22A are independent from each other.
  • the tobacco-wrapping belt 23 is arranged such that the tobacco-wrapping belt 23 wraps the fixed tobacco-wrapping roller 22A and the movable tobacco-wrapping roller 22B. Further, as shown in Fig. 15 and Fig. 16 , the tobacco-wrapping belt 23 has a length which is sufficient for pressing tobacco leaves and a filter for producing one piece of hand-rolled cigarette in a space defined between the fixed tobacco-wrapping roller 22A and the movable tobacco-wrapping roller 22B.
  • the direction that the "length” is taken is perpendicular to the direction that a width "e" shown in Fig. 13 and Fig. 14 is taken.
  • FIG. 15 to Fig. 19 are schematic cross-sectional views of the personal tobacco wrapping device 40 shown in Fig. 13 taken along a line f-f. Firstly, as shown in Fig. 15 , in a state where the fixed tobacco-wrapping roller 22A and the movable tobacco-wrapping roller 22B are separated from each other, a proper amount of tobacco leaves 7A and a columnar filter (not shown in the drawing) are aligned with each other on the tobacco-wrapping belt 23.
  • the tobacco leaves 7A and the filter are pressed into the space defined between two rollers 22A, 22B from above the tobacco-wrapping belt 23.
  • the movable tobacco-wrapping roller 22B is made to approach the fixed tobacco-wrapping roller 22A. In this manner, as shown in Fig. 16 , the tobacco leaves 7A and the filter are accommodated in a space defined below two rollers 22A, 22B.
  • the tobacco-wrapping belt 23 is moved along peripheries of the tobacco leaves 7A and the filter. Due to such movement of the tobacco-wrapping belt 23, the tobacco leaves 7A are formed into a columnar shape together with the filter.
  • a rectangular wrapping paper 2 is inserted into the space through a gap defined between the two rollers 22A, 22B and two rollers 22A, 22B are rotated.
  • the rotational directions of two rollers 22A, 22B are the directions indicated by the arrows in Fig. 16 .
  • an adhesive strip is formed on one end of one surface of the wrapping paper 2.
  • a length of the hand-rolled cigarette is determined based on the inner width "e" of the personal tobacco wrapping device 40 shown in Fig. 13 and Fig. 14 . Accordingly, a length of the filter which is used together with the tobacco leaves is also limited so that a large-sized filter cannot be used in the production of the hand-rolled cigarette.
  • the wrapping paper 2 wraps the tobacco leaves 7A and the filter in several layers. Accordingly, compared with a hand-rolled cigarette where the wrapping paper wraps tobacco leaves and a filter in one layer, the consumption of the wrapping paper in smoking is large and, further, a taste of the hand-rolled cigarette which a smoker enjoys by smoking is spoiled.
  • a reverse wrapping method As a method for producing a hand-rolled cigarette which can suppress the consumption of a wrapping paper and allows a smoker to enjoy a taste of the hand-rolled cigarette by smoking, there has been known a reverse wrapping method.
  • Fig. 20 wrapping of tobacco leaves 7A with a wrapping paper 2 starts from an end portion of the wrapping paper 2 on a side where an adhesive strip 26 is formed in such a manner that a surface of the wrapping paper 2 on which the adhesive strip 26 is formed faces an outer side of tobacco leaves 7A.
  • Fig. 21 and Fig. 22 when the wrapping paper 2 wraps around the tobacco leaves (not shown in the drawing) one time and overlaps with a surface of the adhesive strip 26, the wrapping paper 2 is made wet from outside the overlapped portions thereof so that overlapped portions of the wrapping paper 2 are adhered to each other.
  • Fig. 23 an unnecessary portion of the wrapping paper 2 is cut away.
  • the wrapping paper is inserted into the personal tobacco wrapping device in a state where the surface of the adhesive strip which faces the outside is made wet. In this case, the wrapping paper is adhered to constitutional parts of the personal tobacco wrapping device. For this reason, it is substantially impossible to produce the hand-rolled cigarette by the reverse wrapping method using the personal tobacco wrapping device.
  • an adhesive agent is applied to only one surface of the wrapping paper. Accordingly, a shrinkage rate of the wrapping paper due to drying of the wrapping paper differs between the surface of the wrapping paper to which the adhesive agent is applied and the surface of the wrapping paper to which the adhesive agent is not applied. For this reason, when the wrapping paper is stored for a long time, the wrapping paper curls with the adhesive strip directed inwardly. Accordingly, as shown in Fig. 24 , it is difficult to produce the hand-rolled cigarette by the reverse wrapping method using the wrapping paper 2 which is bent in the direction toward the adhesive strip 26 and a general filter (not shown in the drawing) .
  • a fibrous filter shown in Fig. 25 whichhas a cylindrical shape and is also used in a commercially available cigarette
  • a plastic-made filter shown in Fig. 26 which is called “tip” and has a hollow and substantially frustoconical shape
  • a filter shown in Fig. 27 which is called "roach” and is formed by rolling a rectangular paper 21 in a cylindrical shape.
  • the sizes of all these filters are substantially equal to the size of the filter of the commercially available cigarette.
  • Fig. 27 is a schematic view showing steps of producing the roach. As shown in Fig. 27 , the roach rolled into a columnar shape is produced by rotating the rectangular paper 21.
  • the production of the hand-rolled cigarette using an aluminum-made cylindrical filter shown in Fig. 28 having a diameter "g" of 8mm and a length "h" of 20mm which are substantially equal to corresponding sizes of a filter of a commercially available cigarette is most excellent in terms of an advantage that the filter can be used repeatedly, an advantage that the personal tobacco wrapping device can be used for producing the hand-rolled cigarette, and an advantage that a wrapping paper is completely burnt or tobacco leaves are completely consumed.
  • a substance such as tar which is generated when tobacco leaves are burnt is harmful and spoils tobacco taste is liable to pass the filter. Accordingly, the taste of cigarette is spoiled before the tobacco leaves are not burnt to an area close to the filter. Further, a smoker's lips may feel hot while smoking due to heat conduction from smoke generated by burning of tobacco leaves.
  • a length of the filter is set to approximately 70mm, for example.
  • the elongation of the filter can suppress spoiling of tobacco taste and the excessive heat conduction to the smoker's lips.
  • a commercially available personal tobacco wrapping device does not have a width sufficient to allow the use of the elongated filter and hence, there may be a case where the hand-rolled cigarette cannot be produced using the personal tobacco wrapping device.
  • a smoker produces the hand-rolled cigarette by wrapping tobacco leaves manually with a wrapping paper without using the personal tobacco wrapping device.
  • a surface of the aluminum-made filter is slippery so that the wrapping paper slips on the surface of the filter. Accordingly, it is difficult for the smoker to wrap the tobacco leaves with the wrapping paper. Further, even if the wrapping paper can be wrapped around the filter, the wrapping paper and the tobacco leaves are liable to be removed from the filter.
  • the present invention has been made under such circumstances, and it is an object of the present invention to provide a tobacco filter which enables the easy production of a hand-rolled cigarette without using a personal tobacco wrapping device, can suppress excessive heat conduction to a smoker's lips, and can suppress spoiling of tobacco taste during smoking.
  • a tobacco filter used for producing a hand-rolled cigarette by wrapping at least a portion thereof together with a smoking plant with a wrapping paper, wherein the tobacco filter has an uneven outer surface and a hollow portion which forms a smoke channel, and is made of an incombustible material. Due to the tobacco filter according to one aspect of the present invention, the hand-rolled cigarette can be produced easily, and it is also possible to suppress excessive heat conduction to a smoker' s lips and spoiling of tobacco taste during smoking.
  • the uneven outer surface may be an outer surface on which grooves are formed.
  • An air hole through which air which is taken into the hollow portion from an end portion of the tobacco filter which constitutes a smoker side when the hand-rolled cigarette is produced is guided to the outside may be formed in the tobacco filter at a position in the vicinity of the smoking plant when the hand-rolled cigarette is produced.
  • a diameter of an end portion of the tobacco filter which constitutes a smoking plant side when the hand-rolled cigarette is produced may be set larger than a diameter of the end portion of the tobacco filter which constitutes the smoker side when the hand-rolled cigarette is produced.
  • the tobacco filter may further include an adhesion member which is made of an incombustible material, which is being inserted into the hollow portion during smoking and to which at least a portion of a substance which is produced when the smoking plant is burnt is adhered.
  • the adhesion member may have an elongated plate shape or a shape which is formed by twisting an elongated plate along the longitudinal direction.
  • the tobacco filter may have a multi-faceted columnar profile ranging from a pentagonal columnar profile to an octagonal columnar profile.
  • the hollow portion may have a circular columnar shape. A surface of the hollow portion may be formed of a smooth surface.
  • One of methods which allow a smoker to control an intake amount of nicotine without being controlled by a smoking habit is the use of hand-rolled cigarettes.
  • An operation which produces a hand-rolled cigarette by wrapping a wrapping paper on a smoking plant and a filter takes some time and hence, unless a smoker really wants to smoke, he does not perform a paper wrapping operation. Further, smoking after producing a hand-rolled cigarette by wrapping a wrapping paper on a smoking plant and a filter is impossible during walking or during driving of a car and hence, a smoking amount is surely reduced.
  • the present invention it is possible to easily produce the hand-rolled cigarette which can suppress a change of cigarette taste during smoking without using a personal tobacco wrapping device. Eventually, the smoker can suppress his smoking to an amount not exceeding a necessary amount so that the smoker can reduce his smoking. Further, according to the present invention, it is possible to suppress excessive heat conduction to the smoker's lips. Still further, according to the present invention, tobacco leaves can be completely burnt and the filter can be reused and hence, the reduction of dusts can be realized. Still further, according to the present invention, a smoker produces the hand-rolled cigarette using his finger tips several times every day so that the brain of the smoker is stimulated thus preventing cognitive impairment due to aging.
  • Fig. 1 shows a tobacco filter 1 according to the first embodiment of the present invention.
  • the tobacco filter 1 is used for producing a hand-rolled cigarette which is formed by wrapping a portion thereof together with a smoking plant such as tobacco leaves or smoking herbs with a wrapping paper.
  • the tobacco filter 1 has an octagonal columnar shape shown in Fig. 1 where a diameter "a" of the tobacco filter 1 is set to 4.5mm and a height of the tobacco filter 1 is set to 70mm.
  • a columnar hollow portion having a diameter "b" of 3mm is formed in the tobacco filter 1 as shown in Fig. 1 .
  • the hollowportion functions as a smoke channel 6.
  • the tobacco filter 1 By forming a profile of the tobacco filter 1 into a multi-faceted column such as an octagonal column, at the time of wrapping the wrapping paper around the tobacco filter 1, it is possible to form folding lines inwardly by pushing the wrapping paper onto corner portions of a surface of the multi-faceted column. Accordingly, the hand-rolled cigarette can be easily produced. To prevent an inward folding angle of the wrapping paper from becoming too sharp, it is preferable that the tobacco filter 1 has a multi-faceted columnar profile which is a pentagonal or more columnar profile.
  • the tobacco filter 1 has a multi-faceted columnar profile which is an octagonal or less columnar profile.
  • the multi-faceted column includes a column whose corner portions are curved or rounded.
  • the profile of the tobacco filter 1 is formed of the octagonal column.
  • the profile of the tobacco filter 1 may be formed of an elliptical column, a circular column having one or more corner portions on a side surface thereof or a multi-faceted column.
  • the tobacco filter 1 has an uneven outer surface 4.
  • "outer surface” designates a main surface of the tobacco filter 1 such as side surfaces of the circular column or the multi-faceted column. In other words, the "outer surface” does not include a bottom surface of the circular column or the multi-faceted column.
  • the tobacco filter 1 adopts the outer surface 4 having grooves 5 as the uneven outer surface 4.
  • the grooves 5 are formed in such a manner that the grooves 5 surround the outer surface 4 of the tobacco filter 1. Due to such a constitution, in producing the cigarette by wrapping the wrapping paper around the tobacco filter 1, the wrapping paper is scarcely slipped off from the tobacco filter 1.
  • an outer surface which has asperity such as a saw-toothed shape or a triangular wave shape along the longitudinal direction is named. Further, the asperity may be formed on the outer surface of the tobacco filter 1 along the circumferential direction.
  • the tobacco filter 1 is made of an incombustible material so that a smoker can enjoy smoking by burning substantially all wrapping paper and all tobacco leaves. Accordingly, there is substantially no wasteful consumption of the wrapping paper and tobacco leaves. Further, different from a filter made of paper or the like, the filter made of an incombustible material is not a disposal type but can be reused and hence, the reduction of waste and the preservation of global environment can be realized.
  • the incombustible material metal, ore, ceramics or an inorganic material such as porcelain can be used.
  • the incombustible material may preferably have high thermal conductivity and high formability.
  • respective parts of the tobacco filter may be made of different materials.
  • the tobacco filter may be formed such that a portion of the tobacco filter which touches a smoker's lips is made of a material which has lower thermal conductivity and a portion of the tobacco filter close to tobacco leaves is made of a material which has higher thermal conductivity, or a surface of the tobacco filter is made of a material which has lower thermal conductivity and the inside of the tobacco filter is made of a material which has high thermal conductivity.
  • the tobacco filter 1 of this embodiment is made of 18K gold which is an alloy formed by mixing 15% of silver and 10% of copper into 24K gold.
  • 18K gold which is an alloy formed by mixing 15% of silver and 10% of copper into 24K gold
  • the tobacco filter 1 may be made of other materials such as 18K gold which is an alloy formed by mixing 25% of other metals into 24K gold, pure gold, hardened pure gold with purity of 99.9%, pure silver, silver 925 with a rhodiumplated surface and platinum.
  • 18K gold is superior to 24K gold in terms of high hardness, and silver 925 with a rhodium plated surface is superior to pure silver in terms of oxidation resistance.
  • the thermal conductivity of a surface of silver 925 with a lutetiumplated surface is considerably small compared to the thermal conductivity of the surface of silver 925 with a rhodium plated surface. Accordingly, the tobacco filter 1 made of silver 925 with a lutetium plated surface is superior to the tobacco filter 1 made of silver 925 with a lutetium plated surface in heat insulation in a cooled state. Further, platinum exhibits low thermal conductivity so that platinum is not easily heated whereby platinum is excellent as a material for forming a portion of the tobacco filter 1 which touches a smoker' s lips.

  • the hollow portion formed in the tobacco filter 1 may take any shape. However, it is desirable that the hollow portion has a circular columnar shape. By forming the hollow portion into a circular columnar shape, to focus on the adhesion of a harmful substance such as tar to the surface of the smoke channel 6 during smoking, the harmful substance is adhered to the whole surface of the smoke channel 6 substantially evenly and hence, the smoke channel 6 is scarcely clogged by the harmful substance whereby spoiling of the cigarette taste can be delayed.

Then, two pieces of thus produced members are joined to each other by blazing. Then, an outer surface of the joined members and a surface of a smoke channel 6 formed in the joined members are polished. Finally, rhodium plating is applied to the outer surface of the joined members and the surface of the smoke channel 6.
  • a laser beam is irradiated to an 18K gold ingot which is a material for forming a tobacco filter thus cutting out a cylinder having an inner diameter of 3mm and an outer diameter of 5mm or more (or a thickness of 2mm or more) and a length of 70mm or more.
